CIMAC - pixel clustering, cell clustering (k=10)

• Gaussian blur sigma=2, convert to frequencies before pixel FlowSOM, normalize including calibration channel
• Pixel hClusters found using z-score cap=3, k=20, and iterative thresh=2 (1 iteration)
• Cell-based clustering using frequencing of 20 hClusters (cap): normalize by size
• k=10 for cell clustering
